Autoreactivity vs autoimmunity: characteristics of autoantigen‐specific CD4 T‐cells in rheumatoid arthritis and health.

open access: yesArthritis &Rheumatology, Accepted Article.
Background CD4 T cells specific for citrullinated (cit)‐peptides are key players in RA immunopathogenesis. Characterising these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next generation of RA treatments.

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies

open access: yesArthritis &Rheumatology, Accepted Article.
Background Type I interferonopathies are heterogeneous diseases driven by dysregulated IFN‐I signaling. Diagnosis is challenging due to clinical/molecular variability and the need for IFN‐I quantification. Objective To characterize the clinical, immunological, genetic, molecular profiles of patients with suspected enhanced IFN‐I signaling, and assess ...

Increased plasma microbial tDR‐1 in at‐risk individuals is associated with decreased conversion to clinical rheumatoid arthritis and reduces an in vitro macrophage type 1 interferon response

open access: yesArthritis &Rheumatology, Accepted Article.
Background Microbial small RNAs (sRNAs) can regulate human genes. Higher plasma concentrations of microbial tRNA‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anti‐cyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (ARI)

DNA (cytosine‐5)‐methyltransferase 3A (Dnmt3a) mutations limit normal and autoreactive CD4+ T follicular helper responses and attenuate T cell‐driven joint inflammation

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased inflammatory markers. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the spondyloarthritis (SpA) spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.

Peripheral blood DNA methylation changes precede lymphoma diagnosis in primary Sjögren's disease

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives Primary Sjögren's disease (SjD) is a systemic autoimmune disease associated with an increased risk of lymphoma. The molecular mechanisms underlying lymphomagenesis remain poorly understood, and sensitive biomarkers for early identification of high‐risk patients are lacking.
